@pcmasterrace, Lovely snarks. Let me be your guide;
- Masks do stop the spread, look to the third point as to why,
- You cannot wash your hand and be done with it, you have to use 'soap' as well, this is an enveloped virus, solitary water is effective only against unenveloped virus types,
- It is airborne up to 2 meters, by wearing the mask, we change the air jets, the mask turbulence makes air go swirly and slows its air velocity.
They work in theory as long as they are of medical grade N95 or above, they work as long as everyone wearing them aren't making them useless by constantly adjusting them with their hands, touching their face, touching things in shops, on transport, other people etc and then they become useless, which is most of the time.... Even N95 masks become useless when you factor these things in, I see people messing with their face masks and touching things and then themselves on multiple occasions during a half hour shopping trip, not too mention most people are wearing little more than a cotton t-shirt over their face
I'd rather not wear a cotton T-shirt over my mouth that I'm breathing in pathogens over a long period of time, when I am going to come into contact with many contaminated surfaces throughout a normal day, touching my face, touching surfaces, adjusting my mask etc,I'd rather trust good old mother nature who has been around for billions of years.
Hand washing should be made universal, it's basic hygiene, this has been proven for about 200 years when medical science revealed that soap, water, disinfectant etc were the key to fighting infection and performing successful surgery without dying from gangrene and blood diseases.
And of course the golden 2 metre rule, that get's thrown out of the window the minute you set foot in a supermarket or a bus, tube, workplace etc surely if the velocity was to change then the same particles might not be taking the same path but are very much still present and will indeed take another path depending on airflow and size of the space they are present in, other people nearby, surfaces etc?
